Application filed March 28, 1890. Serial No. 345,749. (No model.)

To all whom it may concern.-

leit known that I, GEORGE BEAMON ALLEN, a citizen of the United States,residing at San Leandro, Alameda county, State of Oalifornia, haveinvented an Improvement in llaling-Presses; and I hereby declare thefollowing to be a full, clear, and exact description of the same.

My invention relates to'baling-presses; and it consists in the novelconstructions, combinations, and arrangements hereinafter fullydescribed, and specifically pointed out in the claims.

The object of my invention is to provide a simple and effective meansfor operating the followers of the press, for providing for the reliefof the power-lever when the pressure on the follower is withdrawn, andfor automatically locking and releasing the feeddoors of the press.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure 1 is a side elevation of my press. Fig. 2 is ahorizontal section of the frame to show the gears and operating-links inplan. Fig. 3 is a top view of the latch mechanism. Fig. 4 is a view ofthe operating-lever E, shown as having started on its movement to theright, as indicated-by the arrow.

A'is the body of the press, having within it a baling-chamber at eachend, provided with suitable discharge-doors a. In these balingchambersare the oppositely-reciprocatin g followers B.

About the center of the press are mounted the powengears, (representedgenerally by C.) These are here shown as being semicircular gearsinterineshing horizontally in pairs. They are all mounted in horizontalplanes, and there are four of them, two being mounted upon a verticalshaft 0 and the other two being mounted on a vertical shaft 0'. The pairof gearsin the same horizontal plane internicsh, as shown. One of thefollowerssay, for example, the one on the right-hand side is connectedby a link D with the upper gear of one vertical pair and by a link Dwith the lower gear of the other vertical pair. The otherfollower--namely, the one on the lefthand side-is connected by a link Dwith the lower gear of the first vertical pair and by a link D with theupper gear of the other vertical pair. These connections are made by thepins d and (Z' in the rims of the gears, the former pins representingthose of the links D and D and the latter pins representing those of thelinks D and D All. these links are branched or double, so as to fit bothabove and below the gear-rims. Now it will be seen that by the movementof these gears in one direction the follower on one side is drivenoutwardly, while the follower on the other side is withdrawn toward thecenter, and by the movement of the gears in the reverse direction thereverse operation takes place, the first follower being withdrawn andthe second driven outwardly.

The first point of advantage to be noticed is that by connecting thefollowers in such a manner as to have the power imparted to them fromeach side equally said followers are driven straight and accurately,avoiding any undue friction in the baling'chanibers. The object inhaving four of these gears is to allow the several links to pass eachother in accomplishing the full movement of the followers. There is apoint of novelty to be noticed of great importance in the relativepositions of the pins d and d, by which the power-links are connectedwith the gears. The pins of the links of both followers are placed toone side of the center planes of the gears. The pins dare on one sideand the pins (1 are on the other side, their distance from the centerplanes being equal, and on account of the position and direction ofmovement of the gears the pins d are placed on the gears nearer theirinner ends, while the pins d are placed toward their outer ends.struction provides for a much greater stroke of the followers than ifsaid connections were placed directly in the center planes, and alsoprovides for the immediate start of one follower on its outward strokebefore the other follower is perceptibly affected to begin its returnmovement.

The gears are operated by the following mechanism: A power-lever E hasits inner end pivoted upon one of the vertical shafts of the gears, hereshown as being applied to the shaft 0. A link F has one end branched orforked and is connected with one end of the upper gear on shaft 0, and asecond link F,lying directly under the first, is similarly Thisconconnected with the corresponding end of the lower gear. The rear endsof these links extend to one side of the lever E, and asinglepinfpassesthrough said ends, said pin being mounted and adapted to slide back andforth in an elongated guide slot or opening a in the lever. A third linkF is similarly connected with the other end of the upper gear, and afourth link F is similarly connected with the corresponding end of thelower gear. The other ends of these links extend to the lever E andreceivea single pin f, which is mounted and adapted to slide in alongitudinal .slot or guide opening c in said lever. Pivoted near theinner end of the lever by a eross-head g is a pawl or catch-bar G, theouter end of which is adapted to bear behind the pinf of the links F andF, and said pawl has a shoulder g, which is adapted to bear behind thepin f of the links F and F when said pawl is swung over. A spring II isconnected to a fixed bearing at one end and has its other end connectedwith the pawl or catchbar, and thetendency of saidspring is to keep thepawl or catch-bar over to its engagement normally against the pin f. Thepawl or catch-bar is swung over to the other side by means of wires orrods I, connected with the ends of its cross-head g, said wires or rodsextending forwardly along the lever E and connected at their forwardends with the arms of a pivoted bell-crank or elbow lever J, wherebythey are adapted to be moved in opposite direction.

The operation of this mechanism is as follows: In Fig. 2 the lever E isshown as having just completed its movement to the left. Now to beginits movement to the right the pivoted bell-crank or elbow J at the outerend of lever E is turned so as to pull upon that rod I, which isfarthest from the press. This will turn the pivoted cross-head g ofcatchbar' G, and will thereby swing said catch-bar over from itsposition shown in Fig. 2 to the position shown in Fig. lthat is to say,its extreme end is thereby removed from contact with pin f and itsshoulder g is thrown in behind pin f, and this movement is against thetendency of spring II, which, as before stated, acts to hold thecatch-bar in the position shown in Fig. 2. Now the lever E is moved onits stroke to the right, as indicated in Fig. 4. In this movement thetendency of pin f is to slide along toward the pivoted end of lever E'that is, inwardlyand the tendency of pin f is to slide outwardly alongthe lever. This tendency of pin f is unchecked; but the tendency off ischecked by its contact with shoulder g of catclrbar G. Therefore thelinks F F are thereby con nected with the lever, and said links, beingnow pulled upon, turn the gears to the left. The links F F being free,their pin f, which at first moves outwardly freely, stops when thearrest of pin f takes place. The parts thus remain in the position ofFig. 4 through-v out the whole stroke of lever E to the right.

When the limit of this stroke is reached and the power on the leverrelieved, the slight expansion of the bale would have a tendency, bythrowing the follower back slightly, to turn back the gears slightly,and thereby suddenly jar or vibrate the lever; but thisbaok movement ofthe gears does not soaffect the lever, for the pin f of links F and Fcan move freely outwardly away from the catch-bars shoulder g, and thepin fof links F F is not limited at all and can play freely inwardly. Toeffect the return-stroke of lever E over to the left, the bell-crank Jis released, and the spring H throws the catch-bar G over again, so thatits shoulder g is removed from pin f and its end is thrown behind pinf.Then the movement begins. and when the now-inwardly-sliding pin f comesagainst the end of the bar Git is stopped, and thereby the links F and Fare connected with the lever E and the gears are turned to the right,the pin f being now free. The parts remain in this position, as is shownin Fig. 2, until the stroke to the left is completed. The gears O areloose on their shafts, and by reason of the opposite connections of thepowerlinks of the followers one horizontal pair of said gears has alwaysa strain upon it; but the other horizontal pair, being independent onthe shafts, can adjust themselves so as to avoid any lost motion in themesh. In the top of the press are the upwardlyswinging feed-doors K.These are automatically raised by means of a crank-weight iv,

a rock-shaft w, carrying a lever w, and a connecting-link 10 betweensaid lever and the doors. The doors are held down by means of slidinglatches L, the ends of which project over the free edges of said doors,and said latches are normally held in a projected position by means ofsprings Z. These latches are alternately withdrawn in order to relievethe doors by the following means: Upon the top of a guide-frame b ofeach follower is a contact-bar Z). Pivoted in the top of the press atthe point on is a swinging lever M, the lower end of which is adapted tobe struck alternately by the contact-bars b of the follower-frames. Overthe upper end of this lever is freely looped an open link N, whichextends in one direction and is connected with one of the latches. Asecond open link N is freely fitted over the top of the lever, andextends in the other direction and is connected with the other latch.Now upon one of the contact-bars coming in contact with the lever saidleveris moved in onev direction so that it pulls upon one of the openlinks, but moves freely in the other, and the one it pulls uponwithdraws its latch. The same operation takes place with the other latchby contact with the other follower.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
